FT-IR spectroscopic investigation of bacterial cell envelopes from Zymomonas mobilis which have different surface hydrophobicities
Abstract Changes in the cell envelope composition of bacteria Zymomonas mobilis 113S which resulted in varied cell surface hydrophobicity (CSH) were examined using FT-IR-spectroscopy and conventionalExpand
Evaluation of novel lactose-positive and exopolysaccharide-producing strain of Pediococcus pentosaceus for fermented foods
The present study confirmed the presence of lactose-positive and exopolysaccharide-producing strain of P. pentosaceus in natural environment which could be used as a starter culture to impart more functional attributes to fermented food. Expand
Hydrophobicity of bacteria Zymomonas mobilis under varied environmental conditions
Abstract Changes in the cell surface hydrophobicity (CSH) of bacteria Zymomonas mobilis 113S were examined in response to varied environmental conditions (temperature and phase of growth,Expand
Formation of Levan from Raffinose by Levansucrase of Zymomonas mobilis
Levansucrase (EC of Zymomonas mobilis 113S can perform the polymerisation of fructose moiety from raffinose to levan concomitantly with a release of non‐catabolised melibiose into theExpand
Relationship between the cell surface hydrophobicity and survival of bacteria Zymomonas mobilis after exposures to ethanol, freezing or freeze-drying
The results suggest that the CSH could be of value to predict the ability of intact bacteria to endure stress conditions and should be monitored towards lower values during cultivation in order to reduce subsequent unwanted structural and physiological disturbances provoked by multiple stress factors.

Molar growth yields of Zymomonas mobilis on glucose after the transition from anaerobic to aerobic continuous growth
The results obtained provide evidence that the increased values of biomass yield could be explained by the redirection of ATP usage during aerobic growth of Z mobilis. Expand
Development of Bifidobacterium lactis Bb 12 on β‐(2,6)‐Linked Fructan‐Containing Substrate
The bifidogenic properties of various fructans, i.e., inulin, levan, fructooligosaccharides (FOS) and fructan syrup, were tested as glucose substitutes in MRS media and were compared concerning their effect on the commercial strain Bifidobacterium lactis Bb 12. Expand
Influence of growth conditions on hydrophobicity of Lactobacillus acidophilus and Bifidobacterium lactis cells and characteristics by FT-IR spectra
In this study we have found, that the values of cell surface hydrophobicity (CSH) of L. acidophilus LA5 and B. lactis Bb12 cells change in response to varied growth conditions – phase of growth,Expand
Response of Zymomonas mobilis levansucrase activity to sodium chloride
An activation of levansucrase-catalysed levan formation by NaCl, KCl and Na2 SO4 (0.03–0.7 M) was observed using cell-free extract of Zymomonas mobilis. A sigmoidal response of the rate ofExpand
Distinctive attributes for predicted secondary structures at terminal sequences of non-classically secreted proteins from proteobacteria
The proposed prediction tool could be used to specify the secretome proteins from genomic sequences as well as to assess the compatibility between secretion pathways and secretion substrates of proteobacteria. Expand
